I'm curious about something I've noticed at the few Irish music jams I've been to. Whether there are fiddles, pipes, dulcimer, whistles, mandolin or concertinas, everyone seems to be playing one song in unison, that is playing the same notes. I would never have thought that would sound very good, but it sure does! The only other notes I've noticed are a drone or the occasional two or three note chord. Is that one of the defining characteristics of traditional Irish music? How do you like to play it?Margarita
